FAQ
What is the value of a 683 capacitor?
68 nF (0.068 µF): 68 × 10^3 pF = 68,000 pF.
What does 683J, 683K or 683M mean?
The letter is the tolerance: J = ±5%, K = ±10%, M = ±20%. The value is still 68 nF.
Can I replace a 683 capacitor with a different type?
Usually, if the capacitance, voltage rating and temperature characteristic are at least as good. Check the rated voltage, and remember ceramic capacitors lose capacitance at high DC voltage.
